Juvenile Fibroadenoma in a Prepubertal Girl With Idiopathic Precocious Puberty: A Case Report Challenging Hormonal Paradigms.

Juvenile fibroadenoma (JF) is a rare benign breast tumor that predominantly occurs in adolescent and young adult females. However, its occurrence in prepubertal girls is exceedingly rare and poses diagnostic and therapeutic challenges. We present a case of a six-year-old girl with a rapidly growing breast mass, ultimately diagnosed as juvenile fibroadenoma. This case highlights the importance of considering JF in the differential diagnosis of breast masses in pediatric patients, even in very young children. The clinical presentation, diagnostic workup, and management of JF are discussed, along with a review of the literature to provide insights into this rare condition.
